Split pea soup is open to lots of interpretations. You can leave out the bacon to make it vegetarian/vegan, or add shredded ham hock meat to the soup after you blend it. (If you choose to do so.) Garnishes could include some toasted seeds, a dab of sour cream, or some crisp bacon strewn over the top. With good bread and cheese, it makes a nice winter meal.
Serving and storage: The soup can be served as is, or you can scatter sliced scallions or chives, nuts or seeds, garlic croutons, crumbled bacon, and perhaps some smoked salt over the top. The soup will keep in the refrigerator for up to four days or can be frozen for several months.
